Specification of Letters Patent.

Application tiled March 7, 1911. Serial No. 612,759.

' Britain, residing at Stype Grange, Hungerford, England, have invented .certain new and useful Improvements in Staples, of

which thefollowing is a specification.

The object of the present invention is to provide an improved staple which can, when required, be easily withdrawn from the wood or other material into which it has been driven.

According to the said invention the improved staple is provided, upon opposite sides or ends ,of the arched head or return end, with projecting ledges, beneath which the claw or forked end of a lever or other extracting tool can be engaged for the purpose of prizing the said staple out of the wood or the like into which it has beeny driven.

Figure lof the accompanying drawings represents the improved staple in elevation, showing a forked extracting lever engaged with the ledges of the head for the purpose of withdrawing the staple. Fig. 2 shows the said staple separately. Fig. 3 is an edge view, illustrating how the forked end of the leverengages below the ledges of the head. Fig. 4 is a vertical section through the said head and extracting lever. Fig. 5 shows edge views ot' the staple and lever when disengaged. Fig. 6 is an underside plan of the staple.

Referring to the drawing the staple,which wise, is of substantially thej ordinary U-shape, but the outer end or head a, above the space inclosed by the sides b, is provided, upon opposite sides, with overhanging projecting ledges a1,which extend across the uppermost part of the staple from side to side, and form, with the inner part a2 of the head, right-angled shoulders adapted to be engaged y the claw or .forked end c* of the extracting lever c or other suitable implement. When the staple is driven into the wood the undersides of the overhanging ledges a1 are separated from the wire which the staple gri s by clearance spaces correspending to t 1e depth of the inner part a? of the head, and when it is desired to remove the said staple the end c1 of the lever c is engaged with the head as shown in Figs. 1, 3, and 4, so that the claws pass one on each s1de of the part a2 and respectively engage beneath the corresponding ledge a. The staple. can then be easily drawn after the manner of a headed nail, although there are no outwardly projecting angles which might injure live-stock.

Preferably, in order to facilitate the insertion of the claw end of the lever, the projections a1 are cut-away or beveled atopposite ends, as indicated at as. y

Having fully described myv invention, what I desire to claimv and secure by Letters Patent is A headless U-shaped staple for fence wires having itsy arched connecting' portion formed upon the o posite side faces thereof with longitudinal edges whose upper and side faces are convexed 'and yconstitute continuations of the convex upper face of said arched portion, and whose flat. under faces are disposed at right angles to the aforesaid side faces of sai arched portion and are remote from the lower edge ofl said arched portion to produce clearancespaces between v the wire and the said under faces, into which spaces the prongs of a forked extractin implement may be inserted said ledges emg disposed wholly within the U out1me of the Sta' le.

n testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
